This special instruction contains the necessary information that is required to bench a specific torque converter arrangement. Refer to Table 2 for the correct arrangements. Bench testing the torque converter ensures correct assembly and operation of the component. Rotating a torque converter provides the most conclusive evaluation. Testing allows the dealer to ensure that the torque converter will operate properly in the machine. The specifications in this guideline are specific to bench testing the component. Every effort has been made in order to provide the most current information that is known to Caterpillar. Continuing improvement and advancement of product design might have caused changes to your product which are not included in this publication. This guideline must be used with the latest technical information that is available from Caterpillar.
For questions or additional information concerning this guideline, submit a form for feedback in the Service Information System. In order to address an urgent need, use the following resources to communicate your request to Caterpillar Repair Process Engineering:

Canceled Part Numbers and Replaced Part Numbers
This document may include canceled part numbers and replaced part numbers. Use NPR on SIS for information about canceled part numbers and replaced part numbers. NPR will provide the current part numbers for replaced parts.
Collecting The Test Data
Since conditions vary for each test bench, use the data that is collected from your test bench. The collected data is used to compare test results. The data should be collected and maintained by the operator.
Data from each transmission arrangement is collected and stored. Averages from each transmission arrangement are often used in order to compare values on portions of transmission tests. Always compare data that is collected from the same transmission arrangement that is being tested. Averages for the last 20 transmission arrangements should be maintained.

Personal injury or death can result from escaping fluid under pressure. Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury. Always use a board or cardboard when checking for a leak. |
 |
|
Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin. |
|
|
Personal injury or death can result from not following the proper procedures. To avoid the possibility of injury or death, follow the established procedure. |
|
Tools Needed
Note: Pressures will be sensitive to tooling setup. The diameter of the hose, the diameter of a fitting, and additional filtering can affect pressure. The required tools that are listed in Table 3 were used in order to develop this test procedure.

Test Procedure
Warm-up Procedure
- If you are using SAE 10W oil, warm the oil to 50 °C (125 °F). If you are using Mobil DTE11 oil, warm the oil to 34 °C (95 °F). Maintain this temperature for the duration of the test.
- Adjust the output flow at the No. 2 flow meter to 106.0 ± 1.89 L/min (28 ± .5 US gpm).
- Rotate the input shaft in a counterclockwise direction. Adjust the input rotation to 1600 ± 20 rpm.
 | |
| Illustration 28 | g02720621 |
- Maintain input speed, oil flow, and pressure for 5 minutes in order to purge the air from the system.
Torque Converter Pressure And Leakage
- Adjust the output flow at the No. 2 flow meter to 106.0 ± 1.89 L/min (28 ± .5 US gpm).
- Adjust the input rotation to 1600 ± 20 rpm.
- Record the torque converter inlet flow at the pressurized flow meter in Table 6.
- Record the torque converter inlet pressure in Table 6.
- Record the torque converter outlet relief pressure in Table 6.
- To obtain the leakage, subtract the output flow from the input flow.
- Record the calculation in Table 6.
Contamination Control
- Drain all oil from the torque converter.
- Take an oil sample of the test bench oil supply. Oil contamination must be below ISO 16/13.
- Record the results in Table 7.
- Remove the torque converter from the test bench if the test bench oil supply is within specifications.
